When an error has occurred, the error code, error
contents, and error's time and date are stored in the
Error Log Area. Information on the 20 most recent
errors can be stored.
Each error record occupies 5 words; the function of
these 5 words is as follows:
1) Error code (bits 0 to 15)
2) Error contents (bits 0 to 15)
Error contents:
Address of Aux. Area word with details or 0000.
3) Minutes (bits 8 to 15), Seconds (bits 0 to 7)
Seconds: 00 to 59, BCD
Minutes: 00 to 59, BCD
4) Day of month (bits 8 to 15), Hours (bits 0 to 7)
Hours: 00 to 23, BCD
Day of month: 01 to 31, BCD
5) Year (bits 8 to 15),
Month (bits 0 to 7)
Year: 00 to 99, BCD
Month: 00 to 12, BCD
Errors generated by FAL(006) and FALS(007) will
also be stored in this Error Log.
The Error Log Area can be reset from a Program-
ming Device.
If the Error Log Area is full (20 records) and another
error occurs, the oldest record in A100 to A104 will
be cleared, the other 19 records are shifted down,
and the new record is stored in A195 to A199.
